To all 117mm 1'1? m (Zj/ concern B it known that I, RALPH W. D UNKLE, a citizen of the United States, residing at Greenville, in the county of Dorks and State of @hio, have invented certain new and useful Improvements in Signol-l'lorns, of which the following a specification.

This invention relates to an improved signal horn which is intended to be used in connection with bicycles, motorcycles and the like and the principal object of the invent-ion is to provide a; horn with improved means for moving the operating mechanism into and out of operative relation to the tire of one of the wheels.

Another object of the invention is to so mount the operating shaftthot it will be norinallv heloi in an inoperative position and. returned to the inoperative position when the actuating lever is released.

Another object of the invention is to so construct the actuating lever that the operating shaft of the horn may return the lever to its normal positioii when iihe actw sting lever is released.

Aiiother object of the. invention is to pro" vide a horn of the (liophrsgm type which will be compact-end so constructed that the opersting mechanism carried by the shaft \Yill'gbfi inclosed sntlthns protected from claniiige by dirt or (lempness.

This invention is illustrated in the acconn punying drawings, wherein- Figure l is a side elevation showing the horn applied to a bicycle; Fig, 2 is a top plan showing the partially in section {and partially in top plan: tll'fi 3 is vies; showing the horn r'tiiilly in longi- "nil nertia v in elevation. th piece of 11 h mes .Ylilifl. pass through the thus secure the lingo/hrs housing; sncl mouth pi 1 \Y'LL'U the o I l or means of s. It should he noteil that the 02211 so shaped. that pressure of the ainst the lreeentl of the finger swing the lever to the position tencl 0 by the diaphragm 13 engages the toothed disk rigidly mounted upon the shaft 18snd it will thus'be seen that when the shaft 18 is rotated that the diaphragm will be vibrated to cause a signal to be sounded. It should be noted that the toothed disk 25 is of such width that the shaft 18 may move to, an operative position Without the pin 24 moving out of engagement with the toothed disk.

Under normal circumstances the shaft 18 will be held in the position shown in 2 and the Wheel 17 can therefore rotate Without the horn being sounded. When it is desired to sound a signal the chain 26 which leacls toe. convenient place such as the han- (lle bars 27 'Will bedroom to. raise the lever 21 and swing the cam finger 20. As the cam finger moves the shaft 18 "will slitle longituclinally through the housing ll thus bringing the friction disk into engage ment with the tire'lti. The shaft 18 will then be rotated thus causing the diaphragm 13 to he 'ibrnterl through the medium of the toothed diskand pin 24 211151 giving out an audible signal. When it is no longer clesired to sound the signal the chain or line 915 is relezisecl and the spring 22 will then move the shaft 18 to the position shown in Fig. and move the disl. 23 out of engage ment with the tire the she moves to the inc-oer tire position i. l of it upon the n so :Zl he signal i ready o, the s e D it would Loreen from op White 1. A comp piece, it (lie-ga ore housing and said diaphragm, anoperating shaft slidably and rotatably carried by said housing, a toothed disk rigidly carried by said shaft and engaging said pin, a spring mounted upon said shaft between said disk and one of the walls of said housing for yieldably holding said shaft in a normal position, a disk secured to one end portion of said shaft outside said housing, a securing bracket carried by said housing, and a lever pivotally connected with said bracket and having one end portion formed into a cam finger engaging said shaft whereby said shaft may be moved to an operative position by movement of said lever and said shaft returned to said normal position by said spring, the shaft acting upon-said cam finger to return said lever to its initial position when said shaft is returned to said normal position.

2. A signal comprising a housing, a vibrat'able element, an actuating shaft slidably and rotatably carried by said housing, means to transmit motion from said shaft to. said vibratable element when said shaft is rotated, resilient means in said housing for yieldably holding said shaft in an inoperative position, meansfor causing said shaft tobe rotated when said shaft is moved to an operative position, and means for moving said shaft to an operative position, said last mentioned means including 'a cam engaging said shaft to move said shaft longitudinally when said last mentioned means is moved, said shaft by engaging saidcam returning said last mentioned means to its initial position when said shaft is moved to an inoperative position by said resilient means.

3. A signal comprising a housing, a diaphragm, a pin carried by said diaphragm,

an operating shaft slidably and rotatablycarried by said housing, actuatin means for said pin, carried by said sha t, resilient means yieldably holding said shaft in anormally inoperative position, and a pivotally mounted lever havlng one .end formed into a cam finger engaging said shaft whereby said shaft may be moved to an operative position by movement of said lever and said shaft returned to its normal position by said resilient means, the shaft acting upon position. v s

4:. A signal comprising a housing, a vibratableelement, an actuating shaft slidably' and rotatably carried by said housing and provided with means to transmit moso cam finger to return said lever t'o its initiai.

tion to said vibratable element when said tudinally toan operative position, said shaft by engaging said cam returning said last mentioned means. to its orig nal position when saldsshaft is moved to an inoperative position by said first mentioned means, and

sound producing 'mea'ns actuated by said shafts In testimony whereof I my signature in presence of two witnesses.
